Unsuspected gallbladder carcinoma during laparoscopic cholecystectomy:An analysis of 16 cases / 中国微创外科杂志

ABSTRACT

Objective To explore the causation as well as the prevention and treatment of unsuspected gallbladder carcinoma (UGC) during laparoscopic cholecystectomy (LC). Methods Clinical data of 16 cases of UGC encountered during 6 031 cases of LC (0.26%) in this hospital were retrospectively reviewed. Results Out of the 16 cases of UGC, 9 were diagnosed intraoperatively and the other 7 were identified by histopathologic examination after surgery. The median survival time was 20.3 months. Of the 15 cases with primary tumor over T 2 stage open operation was performed in 10 cases and the other 5 cases didn’t undergo open surgery after the diagnosis was clarified, the postoperative survival time being (19.9?4.9) and (9.8?2.8) months, respectively; 9 cases underwent radical or aggressive radical cholecystectomy and 6 didn’t undergo redical resection, the postoperative survival time being (21.6?5.3) and (7.8?2.6) months, respectively. Conclusions Recognition and precautions about gallbladder carcinoma should be strengthened before LC. The resected gallbladder should be routinely examined and frozen-section examination should be applied promptly if there have any suspicions of malignancy. Once the UGC is diagnosed, radical or aggressive radical resection should be adopted as early as possible, and necessary measures should be taken to prevent implantation and metastasis of carcinoma.
